Foreign objects in drum, gasket, or pump filter

How to Identify: Intermittent rattles or metallic clinks; small items visible in drum gasket; detected when checking filter or gasket folds.

Part: Drum interior / door seal / drain pump filter

Worn or failed drum bearings

How to Identify: Rumbling or grinding in addition to rattling, louder at higher spin speeds, possible water leaks.

Part: Drum bearings / tub seal

Loose internal counterweights or pulley

How to Identify: Rattling correlated with rotation speed, possible visible looseness when machine opened.

Part: Counterweights / pulley assembly
